the error message is "QuickTime is not installed on this system, some components will not work correctly."

And when I open After Effects CS5 on MacPro 2 x 2.26 GHz Quad-Core Intel Xeon with 16GB of 1066 MHz DDR3 running 10.6.3, it is basically not functionaly, because it will not open any quicktime movies without an error message.

Quicktime is installed on this mac.

I have run permissions and run diskwarrior, and it has not solved this problem.

It was strange, I got the message about a file in the preferences, but there were no files there, even when I used the terminal to look, the files did not exist, so I am wondering if their was some strange preference issue going on.

I also went through, and tried cleaning out my user library a bit, and tried unistalling all the user preference panes, which did not help at all, so I assume that is not the problem, nor was it perian or even Application Enhancer, which are all installed for all users, so then the new user would not work without them.

This morning I decided to try pulling out the entire Adobe Preferences folder, User:Preferences:Adobe and just put back Adobe:After Effects, and After Effects CS5 booted perfectly. It boots quickly and I don't even get the dynamiclinkmanager crash that I have been getting.

And I it seems to have created a new folder in my new Adobe folder, the Adobe QT32server:1.0:TraceDatabase.txt and the dynamiclinkmananger:2.0:memorybalancers5.xml was created this time as well. I then quit after effects, and put back all the other preference files into that folder, though not replacing any of the new versions that were created, and once again After Effect boots and works.

I'm getting the same error on a Mac Pro running Snow Leopard 10.6.3. I tried deleting all of my Adobe preferences, but no luck. I then tried creating a new user account....still no luck. I have both QuickTime X and QuickTime 7 installed on my machine. This is really frustrating and disappointing; I hope Adobe is able to remedy this bug soon.

There are a few things that cause After Effects to report that QuickTime is not installed.

One is the obvious one: If QuickTime 7.x is not installed, After Effects will report that QuickTime is not installed.

The next most common reason is quite different: The TCP communication with the QuickTime server is blocked, so After Effects thinks that QuickTime isn't there at all. The fix for this to remove the blockage in communication. Sometimes the blockage is because of an aggressive firewall program, which sees the TCP communication and stops it. If this is the case, then you can either turn the firewall software off or specifically allow the QT32 Server component to communicate; instructions for letting a specific process communicate are different for each firewall program, so you'll have to look in the documentation for your security software for information about doing that. Here's a document with some more information about this general issue, though it refers to a more serious failure when the blockage happens at a different step in the After Effects startup process: http://kb2.adobe.com/cps/857/cpsid_85711.html

Another reason is that QuickTime can fail to initialize fully because it gets stuck loading a badly written importer component. If you have any AVI importers/codecs on your Mac, this could be the issue. Here's a message that goes into some detail about that: http://forums.adobe.com/message/2808379#2808379

thank you to jonah_lee! i had exactly the same problem and your solution worked for me as well. i'm on a quadcore macpro running 10.6.8 and after effects cs5 (10.0.2). i love adobe products but the bloatware aspect is out of control!

I've been bashing my head against this issue for a while as well: OSX 10.6.8 - Xeon Quad - 10Gb RAM - Kernal booting 32-bit. I had tried all solutions I could find on all Adobe forum threads includuing, delete prefs, disable firewall, new user account, permission, re-install CS5, re-install OSX (which worked for a short period - before I set everything up again).

I've tracked the issue down on my box to a conflict with a 3rd party application "Advanced Web Ranking" - Verison 8.9 at time of writing. This has 3 processes running for scheduled tasks - awrserver, awsscheduler and awswork I killed all 3 before loading After Effects CS5 and it worked instantly both Adobe QT32 Server and dynamiclinkmanager started without issue.

EDIT: Further investigation shows its only awrserver that causes the isssue, the other two can run without a problem.

EDIT2: There is a server config for AWR which lets you change port it uses, default is 7777 - once my scheduled tasks are back to normal tomorrow I will try experimenting see if changing to 7778 fixes the conflict.

My symtoms where QuickTime not installed and You have at least one output module template that refeers to a missing output plug-in error. Neither Adobe QT32 Server nor dynamiclinkmanager processes were running which will be the reson for the errors.

I've also contacted the people who make the software to let them know of the conflict (I'm going to be running on a different box for now).

Thanks, Patrick. I saw a similar problem with FileMaker's web services blocking the TCP port.

Note that this has gotten better with later versions of our software, in that the assignment of ports is more dynamic and therefore it's less likely that the needed communication channel will get blocked by other software.

This "quicktime is not installed" has been driving me crazy, my only recourse this year was to run AE exclusively on a dedicated machine, because I just couldn't figure out what was causing it. Apparently I was looking in all the wrong places (Video software, video codecs, preferences, etc.). It was the damn process from Advanced Web Ranking crashing my dynamiclinkmanager on AE bootup and resulting in the "Quicktime is not installed" error.

I've replicated this a bunch of times today. List all processes via terminal, if the awrserver process is there, AE will throw up a "quicktime is not installed" error. Once I kill the process, AE can boot up normally.

Probably also why this particular situation isn't common, I'm guessing most people aren't running AWR *and* AE on their machines. Really hoping this is the last I'll have to deal with that frustrating error :-)

Didn't work for me, unfortunately. I've tried every single thing in the Troubleshooting Quicktime Errors blogpost to no avail. Still pops up with the "Quicktime is not installed" even though I can open up the Quicktime Player, look at the DLLs, etc... I've got the Windows Firewall completely disabled, no other software on this machine but AE. So frustrating.
